. eccentlcs 17 move the bearings 5. and 6 upward.

rlhe shaft 1,4 :is `,connected lto theoperating mechanism jof V"the Iolls to be later `described, 'by means of a pinion 18 journaledloosely on ,thefshaft l141, jand lprovided with one of nthe sections of clutch l19. -The other section of Athe clutch is feathered onV the shafmald mounted to move toward andy from .the pinion .to ,engage and dseneas'e theclutchsections. .ffhijs clutch isk operated by asuitabl@ treade not Shawn and is re leased .after one-half a revolution ofthe shaft :K14 by mechanism to be described.

Thetreadle is ccnnected with a link ,2Q pivoted at its upper end to a lever 21. This lever, at yits inner end is ,provided with an angular lug 22, which is adapted to engage 21..,Spra11yarransed groeve 2.3 .n/the movable, section `of ythe clutch, under conditions Ito.

be presently mentioned.vv Y d c '-flhe movable section of theclutch sfnormallypressed towardthe fixed section, by coil spring 24, which isarranged between the upper end of the operating ,lever25for the yclutch and the `frame. The leverQ,

which ,is pivoted intermediate its.e1rds,fis'f proifided with a locking pin 26 above its pivotal connection .and ,this pinis ladapted l toenOjaUe :a notch-1n aflockinO larm 27 1votedfto the frame; and connected to the lever 21, f

The operation of'this `mechanism is as through l.the glink`-28, `the locking arm 27,

which will release the locking lug 26, and the spring 24 will immediately swing the lever 25 to move the clutch section into the position of Fig. 10. It will be noticed from an inspection of Fig. 3 that that end of the movable clutch section remote from the pinion 18 has an annular rib and that the groove 23 before mentioned is in this rib, cutting through the rib. The angular lug 22 of the lever 21 normally occupies the position of Fig. 3, that is on the inner side of the rib, and it will be evident that the said lug will prevent engagement of the clutch sections until the lever 21 is swung as above mentioned. The swinging of the said lever moves the lug 22 downward, and the spring 24 at once engages the clutch sections. During a half revolution the clutch sections remain in engagement, but at the end of this time the pin or lug 22 has entered the groove 23, andthe clutch sections are gradually disengaged through the action of the lug 22. The groove 23 is of less depth than the depth o-f the rib, so that when the pin 22 has passed to the inner side of the rib, it will move upward, drawing down the locking arm 26, and locking the clutch in open position.

After the top roll has been lifted, it is essential to lift the pipe to disengage the corrugations thereof from the corrugations of the lower rolls before the pipe can be withdrawn from olf the upper roll. The lifting mechanism is shown more particularly in Figs. 2, 4 and 5. The said mechanism comprises a table 29 having at the side edge 'adjacent to the rolls the concaved or grooved portion 29a for receiving the pipe. The table is pivotally connected to the upper ends of links 30, which are secured to a shaft 31 journaled in the frame below the table and below the rolls. are braced by cross braces 32, and the table is moved toward and between the rolls 1 and 3, by means of a connecting rod 33, which connects the laterally extending arm 34 on one of the links 30 with the bearing 5 for the top roll 1. When the top roll is lifted, the links 30 are swung, and

the portion 29a of the table V29 is introduced Y between the top roll 1 and the lower roll 3, as indicated in Fig. 5. The pipe indicated at 35 is lifted and drops into the grooved portion 29al of the table.

Other mechanism is provided for stripping the pipe from the roll 1 when it has been lifted onto the table. The said mechanism comprises an ejector lever 36, which is connected to the shaft 31 at its lower end by a lost motion connection indicated at 37, and this ejector lever moves in a slot 38 in the portion 29a of the table. It will be noticedfrom an inspection o-f Figs. 4, 5 and 6 that the upper end of the said lever is provided with laterally eXtending pins 39 engagng above and below the edge of the ta- These links ble, and these pins constrain the upper end of the arm to move at the level of the table. The ejecting lever is moved by the bearing 7. The lug 9 of the bearing is connected by a connecting rod 40 with one end of a lever 41 pivoted to the frame, and having at the other end a rod 42. This rod extends through a lateral lug 43 on the lever 36 and a coil spring 44 is arranged between the lug and a stop 45 on the end of the connecting rod. The rodhas another stop 46 on the opposite side of the lug. VxThen the bearing 7 is swung from the position of Fig. 1 to that of Fig. 3, the lever 41 will be swung in a direction to cause the upper end of the lever 36 to swing to the left of Figs. 2 and 3, that is in a direction to strip the finished pipe 35 from offthe roller 1. The connection between the bearing 7 and the lever 36 is a yielding connection, so as to prevent injury to the lever.

Mechanism is also provided for adjusting the front and rear rolls 3 and 2. The mechanism for adjusting the roll 2 is clearly shown in Fig. 9 wherein the roll is journaled in bearings 47 at the upper ends of threaded rods 48. These rods are threaded through bevel gears l 49, which are rotatably connected with the frame, and the bevel gears 49 are engaged by bevel gears 50 on a horizontal shaft 51. Y This shaft 5l is journaled in bearings 52 which are rotatably connected with the `upper ends of threaded rods 53, these rods being threaded through bracket arms 54 on the frame. The arrangement is such that when the rods 53 are turned by their hand wheels, the shaft 51 will be raised or lowered. l/Vhen the shaft 51 is rotated the roll 2 will be raised or lowered, through the threaded rods 43 and the nuts 49. The shaft 51 is rotated in opposite directions by means of sprocket wheels 55 and 56 journaled loosely upon the shaft on opposite sides of a movable clutch section 57 feathered on the shaft. Each of these sprocket wheels has at its inner face the section of a friction clutch, the movable section 57 of the clutch coperating with-the sections of both sprocket wheels. The clutch section 57 is moved in either direction' by an operating lever 58, and it will be obvious that since the wheels 55 and 56 will rotate in opposite directions, when either is secured to the shaft, the shaft will be rotated in the same direction. Thus the roll 2 may be either raised or lowered. The roll 3 is journaled in bearings 59 having guided vertical movement in the frame, and these bearings are connected with 'the upper ends of threaded rods 60 having guided vertical movement in the frame. The lower ends of the rods 60 are threaded through nuts in the Aform of bevel gears 61 and these gears 61 mesh with the gears 62 at the opposite ends of a shaft 63, which tai-5,827*

ismounted kin bearings 64 rotatably 'con nected withV the upper ends of threaded rods 65.- These rods are threaded through bracket arms 66 en the frame, and' it will justed toward and from the roll 1. These sprocket wheels `and 56 are driven by chains 67 and 68 fromY sprocket wheels' 69 and 70, the former being' on the shaft ofY the roll 2, while the latter is rigid witha pinion 71 meshing with a pinion v72 on the shaft ofthe roll 2. Tt will be evident from the description that the shaft 51 may be rotated from the roll 2 directly to cause it to turn in the same direction or from the pinion 71 to causeV the said shaft 51 to be rotated in the opposite direction to the roll 2, as may be desired.' vhe -shaft`63 is rotated by means of interen'gaging gears 73 from a shaft 74 journaled on the frame, and having a hand wheel at its outer end. The gears 73 are on the shafts 63 and 74.

The machine is operated from any suitable source of power by means of a belt (not shown) connected with the belt wheel 75. This wheel 75 is on a stub shaft 76 journaled on the frame, and having at its inner end a pinion 77, which meshes with the pinion 78 on a second shaft 79. The shaft 79 has a pinion 80 which vmeshes with a gear wheel 81 on a shaft 82, supported in a manner to be described, and having a pinion 83, which meshes With a pinion 84 on the roll 3. This pinion 83 also meshes with a pinion 85, secured to a shaft 90 supported in a manner to be presently des scribed, and meshing with a pinion 86 on the roll 1. The pinion 84 also meshes with a pinion 87 on a shaft 88 and the pinion 87 meshes with a pinion 89 on vthe shaft of the roll 2.

Since the rolls 1, 2 and 3 are movable, it is obvious that the pinions 85 and 87 must move with them to retain the meshing relation. lilith this purpose the shaft 90 is supported by links 91 journaled on the shaft of the roll 1, and other links 92 connect the shaft 90 with the shaft 82. This shaft 82 is again supported by links 93 which are journaled on the shaft of the roll 3. The shaft 88 is supported by links 94 and 94a journaled on the shafts of the rolls 3 and 2, respectively. The shafts 90, 82 and 88 are movable, and it will be evident that when the roll 1 is lifted, the upper end of thev links 92 will swing inward, the pinion 85 remaining in mesh with the pinion 86, and the pinion 83 remaining' in mesh with the pinions 85 and 84. When the shaft of the roll 3 is adjusted vertically the pinions 81 and 87 will follow its movement, and when the roll 2 isadjusted vertically the pinion 87 will follow the movement thereof. The pinion 83 also meshes with a gear wheel 95, which is connected withv the shaft 14 by means of a pinion 96y mesh-ing with the pinion 95 and a pinion 18 on the shaft 14. The pinion 18 is loose on the lshaft 14, and may be connected thereto" by fthe clutch 19.`
